the living creatures fall into the following categories
Fishes (animals which can live in water only)
Amphibians (Animals who can live in both water and land
Mammanls (animals which gives birth )
Insects (Cold blooded)
birds (animals which lays eggs and have feathers)
no let your husband decide which category he belongs to

Mammals
Mammals have several unique characteristics that differentiate them from other animals. Most mammals have hair, or fur, covering their body. They are also capable of regulating their body temperature. The mammals metabolism controls heat production, and the sweat glands help cool the body. These allow the mammal to maintain a constant body temperature, regardless of the environmental temperature. One other difference is that mammals give birth to fully formed babies, and the female mammals produce milk to feed their young.
Most mammals walk on 4 legs, with only the humans walking upright on 2 legs. Aquatic mammals have flippers, or fins, for swimming rather than legs. Common mammals include: primates, such humans and monkeys; marsupials; rodents; whales; dolphins; and, seals.
well acording to science were definatley mammals.

Humans are indeed Mammals. The term 'mammal' refers to all animals that possess mammary glands, like breasts or teats. As humans fall into this category, we are definitely mammals.
The only mammal that does not utilise such appendages is the platypus - which secretes its milk through specialised pores on it's ventral (underbelly) surface. (I can't remember if Echidnas also do this or if they have teats - may have to look that one up)
Birds, while warm blooded, are not mammals because they do not lactate to support their offspring. Pigeons and flamingos do produce a milky substance, but this is not an actual lactation and is produced in the gullet, not through mammary glands.
Additionally, to y'all who answered previously:
If only mammals give birth, then how do other animals get born, hmm?
There are viviporous - live bearing - insects, fish and lizards - and they are certainly not mammals. No eggs involved. Check out Guppies (fish), Tsetse flies (insect) and theres a european mountain salamander (lizard), and some sharks and snakes, that all have live young. There are other methods, like ovoviviparity which involves eggs that are broodeed and hatched internally. This is is sometimes found in other lizards, sharks, snakes, and frogs.
Secondly, Echidnas, spiny ant-eaters and playtpus all lay eggs, but since they lactate to feed their young, they are mammals.
Long story short - live birth alone does not a mammal make!

Qualifications for being a mammal:
1. Warm-blooded
2. Hair somewhere on the body
3. Feed young with milk produced in mammary gland (mammary gland is so named because they are found on mammals)
Note: Laying eggs does not exclude a species from being a mammal. The platypus of Australia and the spiny anteater of Africa both lay eggs, and are both mammals. Humans meet the qualifications for being mammals, and are scientifically classified as such.

The mammals are the class of vertebrate animals characterized by:
-The production of milk in females for the nourishment of young from mammary glands present on most species (It varies in monotremes like the platypus) (Check)
-The presence of hair or fur (Check)
-Specialized teeth (Check)
-Three small bones within the ear (Check)
-"Warm-blooded" bodies (Check),
and, in most cases,
-the existence of a placenta in the ontogeny. (Check)
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Primates
Family: Hominidae
Genus: Homo
Species: H. sapiens
Subspecies: H. s. sapiens
There you go, I'm pretty sure we are mammals

Yes we are mammals. We produce children like us (not in an egg for instance), feed our children milk produced by our bodies and are warm blooded creatures.

Those things on the front of your chest, ogled by men and much beloved by cosmetic surgeons are (properly) called _MAMMARY Glands_, and they (milk secreting glands) are one of the things used to define a mammal
